“…The value of the laser differential efficiency is η slope = 52%. The use of active elements with increased transverse dimensions (50–70 mm), as well as an increase in the HIP treatment duration more than 50 h, made it possible to suppress parasitic generation at large diameters of the pump spot . We found out that in the case of 14.5 mm diameter pump spot, the generation energy was 1.52 Joule with a differential efficiency η slope = 53% and the total efficiency for the energy absorbed in the active element equiled η abs ≈ 50% .…”

The theoretical and experimental analysis of the ternary system Zn-Se-Fe for obtaining new fundamental information on phase using X-ray analysis and inductively coupled plasma mass-spectrometry is carried out. New experimental data of isothermal annealing in the Zn-Se-Fe system at the temperatures 730, 814, 1073 K by X-ray studies confirms the reliability of theoretical isothermal sections. The information on Fe solubility and concentrations of native point defects of atomic scale at bi-and monovariant conditions at 1073 and 1273 K have been carried out. Taking into account the new data on phase equilibria, it is possible to fabricate active ZnSe:Fe 2þ elements to create an effective laser operating at the temperature of 300 K with 1.52 Joule emission energy with efficiency of %50% relative to the absorbed energy.

“…As shown in Figure 5, at a lower pump power, the generation appears in the form of a single pulse with an FWHM duration of ~2.8 ns and ~20 μJ energy. Such a single pulse can be further amplified in Fe:ZnSe, excited (e.g., by a pulsed HF laser [4]) to the energies required for light-matter interaction experiments.…”

“…Создание эффективных источников на активных средах ZnSe : Fe 2+ связано как с развитием технологий выращивания легированных кристаллов, так и с вариацией источников возбуждения лазерной генерации. В настоящее время высокие лазерные характеристики (1.4 Дж при η slope = 52% и η abs ≈ 48%) достигнуты, например, на поликристаллических образцах ZnSe, легированных ионами железа методом диффузии [1][2][3]. В качестве источника возбуждения при этом использовался электроразрядный HF-лазер.…”

Spatial distribution of luminescence characteristics of CVD-ZnSe doped with Aluminum and both Aluminum and Iron by thermal diffusion were studied. The diffusion method leads to formation of two areas in crystal volume: (1) area with high aluminum concentration in which the luminescence of defective-impurity centers (DICs) dominates and exciton luminescence is absent and (2) area with low aluminum concentration in which exciton luminescence dominates. The border of two areas recognized on luminescence map is sharp that not corresponded to diffusion nature. The result is explained by assuming the anomalous nature of aluminum diffusion, leading to a sharp change in the aluminum concentration at a certain distance from the doping surface. Method of aluminum doping process applied in present paper leaded to weakens of well-known luminescence suppression effect by iron ions in ZnSe.
